The family Sergestidae provide a unique system for studying the evolution of bioluminescence, with species possessing one of three distinct forms of photophores. This study capitalizes on molecular data to construct a genus-level phylogeny of sergestid shrimp. “Genome skimming” was implemented, capturing mitochondrial genomic data across 19 species. Additional individuals were incorporated through Sanger sequencing of four partial gene regions. The -sergestes group of genera was recovered as non-monophyletic, with the -sergia group of genera being recovered as monophyletic. Ancestral state reconstructions of light organ type indicate the organs of Pesta photophore is the ancestral state for the …
